Pop-idol Minako Aino (known secretly as Sailor V and Sailorvenus) sings the hit "C'est la Vie", which sounds very much like "Sailor V". Her other songs include "Romance" (a reference to the goddess Venus), "Kinsei ni Katagoshi" (which translates as "Venus over the Shoulder") and her album is entitled "Venus", all tongue-in-cheek hints to her secret identity. Minako Aino is Usagi Tsukino's favorite singer.
There was a half hour "Act 0" released around the same time as the other 49 episodes (or "Acts") that explained events just before Act 1 - such as how Minako Aino became Sailor V. This Act also portrays Kunzite, Zoisite, Nephrite and Jadeite as police officers instead of Shittenou (Generals). Jadeite appears to be wearing a police woman's uniform and complains of sexual harassment from Kunzite. And Nephrite ends up taking pills called "Amichan 3000" (a reference to Ami Mizuno/Sailor Mercury's character) to calm his rage.
In Act 33, Zoisite (Yoshito Endoh) tells Jadeite (Jun Masuo) that he was the youngest and looked up to Master Endymion like a big brother. However, according to Naoko Takeuchi in the manga, Zoisite is the youngest Dark Kingdom General at 16-17.
The character of Sailor Luna appears only in the live-action series (she is the human senshi form of the Luna plush cat). The character of Luna did not appear in human form during any of the five seasons of the animated Sailor Moon series, and was seen briefly in the form of a teenage girl/young woman (though not an actual senshi) towards the end of the Sailor Moon S movie. Luna also appears as a human in various acts of the manga (the Sailormoon S movie equivilant, and the last few acts of the Sailorstars Arc) and does have a few attacks of her own in the manga.
On June 2003, Toei held a one-week audition to find candidates for the Pretty Guardian Sailor Moon cast. A total of 1,152 girls auditioned for the roles before Miyû Sawai, Rika Izumi, 'Keiko Kitagawa (I)', Myû Azama and Ayaka Komatsu were selected to play the Sailor Senshi.
